TECHNICAL FIELD

The present disclosure relates to, but is not limited to, the field ofcommunications and, in particular, relates to methods and apparatusesfor sending, configuring and receiving a configuration resource.

BACKGROUND

At present, the new radio (NR) physical layer technology is underdiscussion in the radio access network (RAN) of the 3rd generationpartnership project (3GPP). However, flexibility and efficiency havealways been goals of an NR physical layer design. The pursuit of maximumflexibility by a physical layer reference signal also seems to be atrend. This is because requirements for demodulation reference signalsmay be different in different application scenarios. At a low frequency,the influence of phase noises does not need to be considered duringdemodulation, and this is similar to a reference signal design inlong-term evolution (LTE). However, at a high frequency, a phasetracking reference signal (PTRS) may need to be introduced forestimating the phase noises. This is because at the high frequency, thephase noises will greatly reduce the estimation accuracy of ademodulation reference signal in the time domain, thereby reducingsystem transmission efficiency.

As can be seen from the above, in a scenario of the high frequency andthe phase noises, a simultaneous application of the phase trackingreference signal and time-domain code division multiplexing of anothersignal should be limited, otherwise the system transmission efficiencywill be affected. If a base station has configured the phase trackingreference signal and the time-domain code division multiplexing ofanother signal, a user should change the understanding of thissignaling.

The present disclosure aims at the problem of poor transmissionreliability or a poor transmission quality and the like caused bysimultaneous transmissions of in a time-domain code divisionmultiplexing mode of another signal and the phase tracking referencesignal.

In one example, the transmission apparatus 106 may bea radio frequency (RF) module, which is used for communicating with theInternet in a wireless way.

A signal sending method is provided in this embodiment. FIG. 2 is aflowchart of a signal sending method according to an embodiment of thepresent disclosure. As shown in FIG. 2 , the method includes steps S202and S204 described below.

In step S202, a first configuration resource and a second configurationresource are determined, where a sending mode of a signal sent by usingthe first configuration resource includes a sending mode of time-domaincode division multiplexing, and a signal sent by using the secondconfiguration resource includes a phase tracking reference signal.

In step S204, signals are sent by using the first configuration resourceand the second configuration resource, where a resource intersection ofthe first configuration resource and the second configuration resourcein time domain is an empty set.

In this embodiment, for a same user, a base station does notsimultaneously configure the signal sent by using the firstconfiguration resource and the signal sent by using the secondconfiguration resource to the user. Alternatively, for the same user,the base station configures the signal sent by using the firstconfiguration resource and the signal sent by using the secondconfiguration resource for the user, but the base station does notsimultaneously send the signal transmitted by using the firstconfiguration resource and the signal transmitted by using the secondconfiguration resource to the user. From the perspective of the user,the user does not desire to be simultaneously configured with the signalsent by using the first configuration resource and the signal sent byusing the second configuration resource. Alternatively, the user doesnot desire to simultaneously receive the signal sent by using the firstconfiguration resource and the signal sent by using the secondconfiguration resource.

Through the steps described above, after a sending end determines thefirst configuration resource and the second configuration resource,where the sending mode of the signal sent by using the firstconfiguration resource includes the sending mode of time-domain codedivision multiplexing, and the signal sent by using the secondconfiguration resource includes the phase tracking reference signal, thesending end sends the signals to a receiving end by using the firstconfiguration resource and the second configuration resource, where theresource intersection in the time domain of the first configurationresource and the second configuration resource is the empty set. In thisway, the sending end does not simultaneously send the signal transmittedby using the first configuration resource and the signal transmitted byusing the second configuration resource. Therefore, the problem in therelated art that user experience is affected by simultaneoustransmissions of the phase tracking reference signal and another signalin a time-domain code division multiplexing mode can be solved, thephase tracking reference signal and another signal in the time-domaincode division multiplexing mode are not simultaneously transmitted, andthereby the user experience is improved.

The steps described above may, but may not necessarily, be executed bythe base station.

In one embodiment, the signal sent by using the first configurationresource includes at least one of: an uplink demodulation referencesignal, a downlink demodulation reference signal, a channel stateinformation-reference signal or an uplink control channel.

In one embodiment, the phase tracking reference signal is configuredthrough one of the following signaling: higher-layer signaling, orphysical layer dynamic signaling and the higher-layer signaling. Thehigher-layer signaling here may be signaling at a layer above thephysical layer, e.g., data link layer signaling or medium access mediumlayer signaling.

At least two of orthogonal codes used in code division multiplexing ofthe first configuration resource are used. In this way, at least twoorthogonal codes are used, achieving orthogonality of signals sent byusing the first configuration resource.

In some embodiments, the signal sent by using the first configurationresource uses orthogonal code [1 −1]. The orthogonal code includes anorthogonal cover code, but is not limited to the orthogonal cover code.In one embodiment, a time-domain density of the phase tracking referencesignal is greater than N, where N is a positive number.

A signal receiving method 1 is provided in this embodiment. FIG. 3 isflowchart one of the signal receiving method according to an embodimentof the present disclosure. As shown in FIG. 3 , the process of themethod includes steps S302 and S304 described below. In step S302, afirst configuration resource and a second configuration resource arereceived, where a receiving mode of a signal sent by using the firstconfiguration resource includes a receiving mode of time-domain codedivision multiplexing, and the signal sent by using the secondconfiguration resource includes a phase tracking reference signal.

In step S304, signals sent by using the first configuration resource andthe second configuration resource are received, where a resourceintersection of the first configuration resource and the secondconfiguration resource in time domain is an empty set.

The signal sent by using the first configuration resource includes atleast one of: an uplink demodulation reference signal, a downlinkdemodulation reference signal, a channel state information-referencesignal or an uplink control channel.

In some embodiments, the phase tracking reference signal is determinedthrough one of the following signaling: higher-layer signaling, orphysical layer dynamic signaling and the higher-layer signaling.

In some embodiments, a time-domain density of the phase trackingreference signal is greater than N, where N is a positive number.

In some embodiments, at least two of orthogonal codes used in codedivision multiplexing of the first configuration resource are used.

The signal sent by using the first configuration resource usesorthogonal code [1 −1]. In this embodiment, a signal multiplexing modein the above steps of the present disclosure is generally defined onadjacent or consecutive time-domain symbols; since the signal sent byusing the first configuration resource on inconsecutive time-domainsymbols has a poor time-domain code division multiplexing effect, thesignal sent by using the first configuration resource is configured onmultiple consecutive time-domain symbols.

Through the steps described above, after a receiving end receives thefirst configuration resource and the second configuration resource,where the first configuration resource includes the receiving mode ofthe signal, the receiving mode includes the receiving mode oftime-domain code division multiplexing, and the signal sent by using thesecond configuration resource includes the phase tracking referencesignal, the first configuration resource is configured according towhether the signal sent by using the first configuration resource andthe signal sent by using the second configuration resource overlap inthe time domain. Therefore, the problem in the related art that userexperience is affected by simultaneous reception of the phase trackingreference signal and another signal in the time-domain code divisionmultiplexing mode can be solved, and thereby the user experience isimproved.

The steps described above may, but may not necessarily, be executed by aterminal.

In one embodiment, when the signal sent by using the first configurationresource and the signal sent by using the second configuration resourceoverlap in the time domain, configuring the first configuration resourceincludes: changing the receiving mode in the time domain of the signalsent by using the first configuration resource from the code divisionmultiplexing to another mode other than the code division multiplexing.

In one embodiment, when the signal sent by using the first configurationresource and the signal sent by using the second configuration resourceoverlap in the time domain, configuring the first configuration resourceincludes: increasing a processing delay for demodulating the signal sentby using the first configuration resource.

In one embodiment, when the signal sent by using the first configurationresource and the signal sent by using the second configuration resourceoverlap in the time domain, configuring the first configuration resourceincludes: the phase tracking reference signal being quasi-co-located(QCL) with the signal on the first configuration resource.

In one embodiment, the signal includes at least one of: the uplinkdemodulation reference signal, the downlink demodulation referencesignal, the channel state information-reference signal or the uplinkcontrol channel.

In one embodiment, the phase tracking reference signal is determinedthrough one of the following signaling: the higher-layer signaling orthe physical layer dynamic signaling.

In the related art, due to a flexible pattern design of the demodulationreference signal, large physical layer dynamic signaling overheads arerequired for dynamically notifying parameters of the demodulationreference signal. How to reduce the overheads without reducing thetransmission efficiency also becomes a big problem. The technicalsolution to the problem of large overheads for configuring or receivingthe demodulation reference signal described above is described below.

The configured relationship between the demodulation reference signaland the corresponding data refers to at least one of: whether amultiplexing mode of the demodulation reference signal and thecorresponding data includes FDM, or a power parameter ratio of thedemodulation reference signal to the data. When the number of symbols ofthe configuration resource is greater than X1, the multiplexing mode ofthe demodulation reference signal and the corresponding data does notinclude the FDM. When the number of symbols of the configurationresource is less than or equal to X1, the multiplexing mode of thedemodulation reference signal and the corresponding data includes thefrequency division multiplexing (FDM).

When the number of symbols of the configuration resource is greater thanX1, the power parameter ratio of the demodulation reference signal tothe corresponding data is greater than Y; when the number of symbols ofthe configuration resource is less than or equal to X1, the powerparameter ratio of the demodulation reference signal to the data is lessthan or equal to Y, where Y is an integer.

The number of symbols of the configuration resource refers to the numberof time-domain symbols included in the sending unit or the number oftime-domain symbols included in the scheduled resource allocated to thesecond communication node in the sending unit.

In this case, the configuration resource refers to the number oftime-domain symbols of the demodulation reference signal included in thesending unit, and the number is less than X3, where X3 is an integer.

When the number of symbols of the configuration resource is less thanX2, the multiplexing mode of the demodulation reference signal and thecorresponding data does not include the FDM. When the number of symbolsof the configuration resource is greater than or equal to X2, themultiplexing mode of the demodulation reference signal and thecorresponding data includes the FDM.

When the number of symbols of the configuration resource is less thanX2, the power parameter ratio of the demodulation reference signal tothe corresponding data is greater than Y; when the number of symbols ofthe configuration resource is greater than or equal to X2, the powerparameter ratio of the demodulation reference signal to the data is lessthan or equal to Y, where Y is an integer.

In this case, the number of symbols of the configuration resource refersto the number of time-domain symbols of the demodulation referencesignal included in the sending unit. Moreover, the number of time-domainsymbols included in the sending unit or the scheduled resource isgreater than X4, where X4 is an integer.

When the configuration resource refers to the time-domain spacing of thedemodulation reference signal in the sending unit, if the spacing isless than Z, the multiplexing mode of the demodulation reference signaland the corresponding data does not include the FDM, where Z is aninteger. If the spacing is greater than or equal to Z, the multiplexingmode of the demodulation reference signal and the corresponding dataincludes the FDM.

When the configuration resource refers to the time-domain spacing of thedemodulation reference signal in the sending unit, the power parameterratio of the demodulation reference signal to the corresponding data isgreater than Y if the time-domain spacing is less than Z. If thetime-domain spacing is greater than or equal to Z, the power parameterratio of the demodulation reference signal to the corresponding data isless than or equal to Y.

A method for receiving a signaling configuration of power of ademodulation reference signal will be described from the perspective ofa receiving end. The method may include the content described below.

A relationship between the demodulation reference signal andcorresponding data, and the number of time-domain symbols of aconfiguration resource, which are jointly configured, are received. Thenumber of time-domain symbols of the configuration resource includes atleast one of: the number of time-domain symbols included in a receivingunit, the number of time-domain symbols of the demodulation referencesignal included in the receiving unit, the number of time-domain symbolsincluded in a scheduled resource allocated to a second communicationnode in the receiving unit.

The configured relationship between the demodulation reference signaland the corresponding data refers to at least one of: whether amultiplexing mode of the demodulation reference signal and the dataincludes FDM, or a power parameter ratio of the demodulation referencesignal to the data.

When the number of symbols of the configuration resource is greater thanX1, the multiplexing mode of the demodulation reference signal and thecorresponding data does not include the FDM. When the number of symbolsof the configuration resource is less than or equal to X1, themultiplexing mode of the demodulation reference signal and thecorresponding data includes the frequency division multiplexing (FDM).

When the number of symbols of the configuration resource is greater thanX1, the power parameter ratio of the demodulation reference signal tothe corresponding data is greater than Y; when the number of symbols ofthe configuration resource is less than or equal to X1, the powerparameter ratio of the demodulation reference signal to the data is lessthan or equal to Y, where Y is an integer.

In this case, the number of symbols of the configuration resource refersto the number of time-domain symbols included the receiving unit or thenumber of time-domain symbols included in the scheduled resourceallocated to the second communication node in the receiving unit.Moreover, the number of time-domain symbols of the demodulationreference signal included in the receiving unit is less than X3.

When the number of symbols of the configuration resource is less thanX2, the multiplexing mode of the demodulation reference signal and thecorresponding data does not include the FDM. When the number of symbolsof the configuration resource is greater than or equal to X2, themultiplexing mode of the demodulation reference signal and thecorresponding data includes the FDM.

When the number of symbols of the configuration resource is less thanX2, the power parameter ratio of the demodulation reference signal tothe corresponding data is greater than Y; when the number of symbols ofthe configuration resource is greater than or equal to X3, the powerparameter ratio of the demodulation reference signal to the data is lessthan or equal to Y, where Y is an integer.

In this case, the number of symbols of the configuration resource refersto the number of time-domain symbols of the demodulation referencesignal included in the receiving unit. Moreover, the number oftime-domain symbols included in the receiving unit or the scheduledresource is greater than X4.

The first communication node may be a base station, and the secondcommunication node may be a terminal.

This embodiment provides a method for sending a configuration of relatedsignaling. The method includes steps described below.

A first configuration resource is determined, where a signal sent byusing the first configuration resource adopts a sending mode oftime-domain code division multiplexing.

A second configuration resource is determined, where a signal sent byusing the second configuration resource includes a phase trackingreference signal and the phase tracking reference signal exists. Anintersection in the time domain of the first configuration resource andthe signal sent by using the second configuration resource in timedomain is an empty set.

A first communication node configures the first configuration resourceand the second configuration resource for a second communication node.That is, a base station configures time-domain multiplexing modes ofsome signals for a user via the first configuration resource. Thesesignals include one or more of an uplink demodulation reference signal,a downlink demodulation reference signal (DMRS), a channel stateinformation-reference signal (CSI-RS) or a physical uplink controlchannel (PUCCH). The base station configures the phase trackingreference signal for the user via the second configuration resource.When signals in a set of first configuration resources and signals in aset of second configuration resources are sent, the signals have nointersection in the time domain. That is, if the phase trackingreference signal (PTRS) is configured for the second configurationresource, a time-domain multiplexing mode configured for the signal sentby using the first configuration resource cannot be code divisionmultiplexing. In other words, the user does not desire to be configuredto simultaneously receive the phase tracking reference signal andreceive the signal sent by using the first configuration resource, wherethe signal sent by using the first configuration resource uses thetime-domain code division multiplexing. In particular, too great adensity of the phase tracking reference signal results in seriousphase-noise influence, so code division demodulation cannot besimultaneously used. If a UE can simultaneously receive the configuredphase tracking reference signal and another signal adopting the sendingmode of time-domain code division multiplexing, some parameters of thePTRS and another signal quasi-co-located (QCL) with the PTRS have to beassumed to be the same, or the time-domain multiplexing mode of anotherreference signal has to be changed from a code division mode to anothermode.

The code division mode in this embodiment refers to that multiple codes,instead of merely one code, included in an orthogonal code may beapplied. That is, at least two orthogonal codes are used in the codedivision multiplexing.

For example, a code length of an orthogonal cover code (OCC) is 2, andthen the code division multiplexing mode refers to that both [1 1] and[1 −1] may be used. If the user or a demodulation reference signal portcan only use [1 1], the mode is practically a simple repetition in thetime domain and cannot be regarded as the code division multiplexingmode. Alternatively, for the OCC with the length of 2, only whensequence [1 −1] can be applied, the mode is regarded as the codedivision multiplexing. If sequence [1 1] is configured, the mode cannotbe regarded as the code division multiplexing (CDM) in this embodimentand is simple repeated transmission.

FIG. 6 is a schematic diagram of the demodulation reference signal inthis embodiment. As shown in FIG. 6 , when the demodulation referencesignal generally occupies two adjacent time-domain symbols, differentdemodulation reference signals may be simultaneously transmitted in thecode division multiplexing mode in the time domain, and demodulationreference signal ports using the code division multiplexing occupy asame time-frequency resource. For example, if port 1 and port 2 are codedivision multiplexed in the time domain, e.g., by using the OCC, port 1may use OCC sequence [1 1], port 2 may use OCC sequence [1 −1], and port1 and port 2 occupy two adjacent time-domain symbols on a samesubcarrier. The advantage of time-domain code division is code divisiongains, which is quite beneficial on a low frequency band.

However, on a high frequency band, due to the influence of phase noises,the application of the time-domain OCC will be affected in the casewhere two adjacent OFDM symbols are configured for the reference signalfor DMRS transmission. This is because the phase noises will generatephase rotations for channels of different OFDM symbols, so that channelson adjacent OFDM symbols are different, degrading channel estimationperformance. Therefore, when the phase noises exist at the highfrequency, it is better not to use the time-domain OCC. Time divisionmultiplexing (TDM) or simple repeated calculations may be used (or onlysequence code [1 1] is used and [1 −1] is not used).

Similarly, for another signal, such as the CSI-RS or the PUCCH, whetherthe multiplexing mode in the time domain adopts the time-domain OCCdepends on the influence of the phase noises. The PUCCH is an uplinkcontrol channel used by the user to feed back an acknowledgement ornon-acknowledgement (ACK or NACK) or CSI. In general, since the PUCCHwith a long format may occupy multiple time-domain symbols, whether theinfluence of the phase noises exists needs to be considered fordetermining whether to adopt the OCC in the time domain. Similarly, ifthe CSI-RS occupies multiple time-domain symbols in the time domain,whether the influence of the phase noises exists also needs to beconsidered for determining whether to adopt the time-domain OCC.

At the high frequency, if the influence of the phase noises exists, thebase station will configure the phase tracking reference signal for theuser through higher-layer signaling, e.g., RRC signaling, to prove theexistence of the phase noises. Due to the existence of the phase noises,the time-domain code division cannot work well, so the base stationshould not configure, for the user, the demodulation reference signal,the CSI-RS, the PUCCH or the like with the code division multiplexing asthe time-domain multiplexing mode, but should configure othertime-domain multiplexing modes for these signals, e.g., the timedivision multiplexing (TDM) or simple port repetitions. In other words,the user does not desire to be simultaneously configured with the phasetracking reference signal and another reference signal whose portmultiplexing mode in the time domain is the code division multiplexing.In this case, the phase tracking reference signal is configured by thebase station through the higher-layer signaling. Therefore, the basestation can make limitations. That is, the base station cannotsimultaneously configure the phase tracking reference signal to betransmitted and another reference signal adopting the sending mode oftime-domain code division multiplexing. Another reference signalincludes at least one of: the uplink demodulation reference signal, thedownlink demodulation reference signal, the channel stateinformation-reference signal (CSI-RS) or the physical uplink controlchannel (PUCCH). It is worth noting that the base station configures thephase tracking reference signal for the user through the higher-layersignaling, which does not necessarily prove the existence of the phasetracking reference signal. In this case, it can only prove the possibleexistence of the phase noises, and whether the PTRS is practically sentis also related to other physical layer dynamic signaling. This isbecause the phase noises are not required when the data corresponds tosmaller bandwidth and a lower modulation and coding scheme (MCS).

In addition, the higher-layer signaling for configuring the phasetracking reference signal not only includes an indication whether theconfigured phase tracking reference signal exists, but also includes alevel threshold of the MCS, a PTRS density (generally referring to atime-domain density) corresponding to the level threshold of the MCS, alevel threshold of resource allocation bandwidth, and a PTRS density(generally referring to a frequency-domain density) corresponding to thelevel threshold of the resource allocation bandwidth. For example, thelevel threshold of the MCS includes multiple values, MCS1, MCS2 andMCS3, and different level thresholds of the MCS represent differenttime-domain densities of the phase tracking reference signal. If thePTRS configured through the higher-layer signaling exists and the MCSallocated by the base station to the user is higher in practicalresource scheduling, e.g., the scheduled and allocated MCS is greaterthan MCS3, the time-domain density of the phase tracking referencesignal should be 1, that is, the PTRS exists on each time-domain symbol.If the MCS allocated by the base station to the user is not so high,e.g., the allocated MCS is less than MCS3 and greater than MCS2, thetime-domain density of the phase tracking reference signal is lessthan 1. That is, the PTRS exists on each two time-domain symbols, andthe time-domain density of the PTRS is regarded to be 0.5. If the MCSallocated by the base station to the user is lower, e.g., the allocatedMCS is less than MCS2 and greater than MCS1, the time-domain density ofthe phase tracking reference signal should be the lowest. That is, thePTRS exists on each four time-domain symbols, and the time-domaindensity of the PTRS is regarded to be 0.25. If the MCS allocated by thebase station to the user is quite low, e.g., the allocated MCS is lowerthan MCS1, the time-domain density of the phase tracking referencesignal should be the lowest, that is, no PTRS is transmitted. Since thelevel threshold of the MCS is configured by the base station through thehigher-layer signaling, the level threshold of the MCS is changeable.

Only considering that the first configuration resource and the secondconfiguration resource are sent to the receiving end when the phasetracking reference signal has a greater density, where the resourceintersection in the time domain of the signal sent by using the firstconfiguration resource and the signal sent by using the secondconfiguration resource is the empty set, and that the existence of thephase tracking reference signal is determined through the higher-layersignaling, the higher-layer signaling in this case includes one of:whether the phase tracking reference signal in the higher-layerconfiguration exists, an MCS level in the higher-layer configuration andthe corresponding PTRS density, or an allocation bandwidth level and thecorresponding PTRS density. The time-domain density of the phasetracking reference signal is greater than N, which means that PTRSdensities corresponding to certain levels of the MCS have to be greaterthan N. For example, the time-domain density has to be equal to 1. Forthe configuration of the phase tracking reference signal, the basestation configures, through the higher-layer signaling and the physicallayer dynamic signaling (the MCS scheduled and allocated to the user,and scheduled bandwidth), whether the phase tracking reference signal istransmitted and the time-domain density of the PTRS in some embodiments.In this case, even if the base station configures the PTRS through thehigher-layer signaling, the PTRS exists only when the bandwidth and theMCS allocated to data by the physical layer are greater than theirthresholds separately. Otherwise, even if the PTRS is configured throughthe higher-layer signaling, the PTRS is not to be sent when thebandwidth and the MCS allocated to the data are smaller. Of course, ifthe PTRS configured through the higher-layer signaling does not exist,the PTRS will not be sent, and the physical layer dynamic signaling isnot involved. Therefore, in practice, if the base station configuresreal transmission of the PTRS through the higher-layer signaling and thephysical layer dynamic signaling, the phase noises are certain to existand the time-domain code division cannot work well. In this case, thebase station should not configure, for the user, the demodulationreference signal, the CSI-RS, the PUCCH or the like with the codedivision multiplexing as the time-domain multiplexing mode, but shouldconfigure other time-domain multiplexing modes for these signals, e.g.,the TDM or the simple port repetitions. In other words, the user doesnot desire to be simultaneously configured with the phase trackingreference signal and another reference signal whose port multiplexingmode in the time domain is the code division multiplexing. In this case,the phase tracking reference signal is configured by the base stationthrough the higher-layer signaling and the physical layer dynamicsignaling. In other words, when the scheduled bandwidth or the MCSdynamically allocated to the user should be greater than certain levelthresholds configured through the higher-level signaling, the PTRSdynamically exists, and the user does not desire the reference signaltransmitted by using the first configuration resource to simultaneouslyexist. Therefore, the base station can make limitations. That is, thebase station cannot simultaneously configure the phase trackingreference signal to be transmitted and another reference signal adoptingthe sending mode of time-domain code division multiplexing. In someembodiments, considering that the time-domain CDM may work when thedensity of the PTRS existing dynamically is not great, furtherlimitations may be made. That is, when the PTRS dynamically allocated tothe user exists and the time-domain density is greater than N, the userdoes not desire the reference signal transmitted by using the firstconfiguration resource to simultaneously exist. In this case, thescheduled MCS for the user is greater than one level threshold, and thetime-domain density of the PTRS corresponding to the threshold is N.

Further explanation for the above two paragraphs is made as follows:since the level threshold of the MCS is configured by the base stationthrough the higher-layer signaling, the level threshold of the MCS haschangeable values. For example, the time-domain density of the PTRScorresponding to the highest value of the level threshold of the MCS isstill quite small, that is, the scheduled MCS for the user is greaterthan the highest level threshold, e.g., MCS 3, and the PTRS density isstill quite small, e.g., 0.5 or 0.25. In this case, it can be regardedthat the phase noises has little influence or that no phase noiseexists, and the user may estimate a Doppler influence, instead of theinfluence of the phase noises, by using the PTRS. In this case, even ifthe higher-layer configuration of the PTRS exists and the scheduled MCSis higher, that is, the PTRS is transmitted, the time-domain codedivision may be applied. Only when the configured phase trackingreference signal has a great density, it is regarded that the phasenoises exist, and the time-domain code division does not work so well.For example, the density of the phase tracking reference signalcorresponding to the level threshold of the MCS in the higher-layerconfiguration is great, e.g., equal to 1, that is, the density isgreater than N, where N=0.5. In other words, the user does not desire tobe simultaneously configured with the phase tracking reference signaland another reference signal whose port multiplexing mode in the timedomain is the code division multiplexing. In this case, theconfiguration of the phase tracking reference signal includes thedensity greater than N. That is, the time-domain density of the PTRScorresponding to the highest level threshold of the modulation andcoding scheme (MCS) is greater than N.

Of course, in some cases where the configuration of the phase trackingreference signal includes the density greater than N, if the scheduledMCS for the user is always lower, the time-domain density of the phasetracking reference signal practically dynamically transmitted is alsosmaller, i.e., less than or equal to N. In this case, it is regardedthat the time-domain code division can also work. Therefore, only whenthe density of the phase tracking reference signal practicallydynamically transmitted is greater than N, e.g., N=0.5, that is, thePTRS density is equal to 1, the time-domain code division cannot work.Therefore, the base station will not simultaneously configure the PTRSand another signal with the time-domain code division, and in this case,the PTRS density is greater than N. In other words, the user does notdesire to be simultaneously configured with the phase tracking referencesignal and another reference signal whose port multiplexing mode in thetime domain is the code division multiplexing. In this case, the densityof the phase tracking reference signal dynamically transmitted isgreater than N.

In addition, the time-domain density of the phase tracking referencesignal is related to the time-domain code division multiplexing of asignal transmitted by using a configuration resource. If the time-domaindensity of the phase tracking reference signal is 0.25, that is, onePTRS RE is sent on each four time-domain OFDM symbols, the phase noisesin the time domain is regarded to be not serious and have littleinfluence phases on adjacent OFDM symbols, so the time-domain codedivision multiplexing of the signal transmitted by using theconfiguration resource can also work when a length of the time-domaincode division multiplexing is 2. That is, OCC 2 may be applied. If thetime-domain density of the phase tracking reference signal is 1, thetime-domain code division multiplexing cannot be applied, and it can beunderstood that a length of the OCC used for the code divisionmultiplexing is 1. Therefore, another signaling configuration method isdetermining a first configuration resource and a second configurationresource, where a sending mode of a signal sent by using the firstconfiguration resource includes a sending mode of time-domain codedivision multiplexing, and the second configuration resource includes aconfiguration of a phase tracking reference signal; and a code lengthadopted by time-domain code division multiplexing of the signal sent byusing the first configuration resource has a correspondence with atime-domain density of a signal sent by using the second configurationresource. The code length of the code division multiplexing may have avalue among 1, 2 and 4. If the code length is 2, a code includes [1 1]and [1 −1]. If the code length is 4, the code includes [1 1 1 1], [1 −11 −1], [1 1 −1 −1] and [1 −1 −1 1].

Of course, from the perspective of a receiving end of a user, in someembodiments, a base station may simultaneously configure the phasetracking reference signal and another reference signal whose portmultiplexing mode in the time domain is code division multiplexing, butthe user may have different understandings, which may include schemesdescribed below.

Scheme 1: The user regards that no phase tracking reference signal isconfigured, that is, phase noises have little influence, so the userregards that no PTRS is configured through higher-layer signaling, orconfigured through the higher-layer signaling and physical layersignaling.

Scheme 2: When the user receives another reference signal, thetime-domain multiplexing mode of another reference signal is changedfrom the time-domain code division multiplexing to another multiplexingmode.

Scheme 3: If the user simultaneously receives the configured phasetracking reference signal and another reference signal adopting thesending mode of time-domain code division multiplexing, a processingdelay required by the user for demodulating another reference signal isincreased. In this case, the user may regard that the phase noisesestimated through the PTRS may be used for demodulating anotherreference signal. The user needs to first demodulate the PTRS and thenuse a demodulation result for demodulating another RS, so a greaterprocessing delay is required. In the case of a demodulation referencesignal, more time may be required for the user to feed back acorresponding ACK or NACK. In the case of a CSI-RS, the user also needsmore time to feed back CSI, and the time for feeding back the CSI islonger than a delay originally predefined or configured.

Scheme 4: Based on scheme 3, if an estimation result of the PTRS is tobe used for estimating another RS, e.g., the CSI-RS, and the time-domainmultiplexing mode of the CSI-RS is the code division multiplexing, ithas to be assumed that the PTRS and the CSI-RS are sent by the sameantenna element, so that the estimation result of the phase noises canbe shared. Therefore, some parameters of the QCL assumptions the PTRSand the CSI-RS have to be assumed to be the same. In other words, if QCLassumptions of the PTRS and the CSI-RS are different, the time-domainmultiplexing mode of the CSI-RS cannot be the code divisionmultiplexing. From the perspective of the user, the user does not desireto be simultaneously configured with the phase tracking reference signaland another reference signal whose port multiplexing mode in the timedomain is the code division multiplexing, and some specific QCLparameters of another reference signal and the PTRS are different, e.g.,a QCL assumption related to a beam at the receiving end. It is worthnoting that QCL parameters may include multiple types of parameters, andthe present disclosure emphasizes that the PTRS and the CSI-RS areassociated and that some specific parameters are the same. Therefore, ifthe first configuration resource and the second configuration resourceoverlap in the time domain, the phase tracking reference signal has tobe QCL with the signal sent by using the first configuration resource.

In this embodiment, a first communication node jointly configures arelationship between the demodulation reference signal and correspondingdata, and the number of time-domain symbols of a configuration resource.The number of time-domain symbols of the configuration resource includesat least one of: the number of time-domain symbols included in a sendingunit, the number of time-domain symbols of the demodulation referencesignal included in the sending unit, or the number of time-domainsymbols included in a scheduled resource allocated in the sending unit.The configured relationship between the demodulation reference signaland the corresponding data refers to at least one of: whether amultiplexing mode of the demodulation reference signal and the dataincludes FDM, or a power ratio of the demodulation reference signal tothe data. The sending unit may be one slot or multiple slots. The powerratio is described for a demodulation reference signal port. A firstdemodulation reference signal and corresponding data refers to that thefirst demodulation reference signal is used for demodulating thecorresponding data layer. That is to say, the demodulation referencesignal and the corresponding data use the same precoding or correspondto a same port.

When the number of symbols of the configuration resource is greater thanX1, the multiplexing mode of the demodulation reference signal and thecorresponding data does not include the FDM, where the number of symbolsof the configuration resource refers to the number of time-domainsymbols included in the sending unit or the number of time-domainsymbols included in the scheduled resource allocated to a secondcommunication node. In this case, when the number of symbols of theconfiguration resource is greater than X1, the power ratio of thedemodulation reference signal to the corresponding data is greater thanY; and when the number of symbols of the configuration resource is lessthan or equal to X1, a power parameter ratio of the demodulationreference signal to the data is less than or equal to Y, where Y is aninteger. Moreover, in this case, there is a limitation that the numberof time-domain symbols of the demodulation reference signal included inthe sending unit is less than X3, where X1, X2 and Y are all integers.

FIG. 7 is a schematic diagram of a transport block size in thisembodiment. As shown in FIG. 7 , if a size of the configuration resourcerefers to the number of time-domain symbols included in a slot, thenumber of symbols included in the slot is 14, i.e. greater than X1,where X1 may be a number less than 14, e.g., 8. In this case, the numberof symbols occupied by the demodulation reference signal is 1. In thiscase, although one time-domain symbol of the demodulation referencesignal may support six ports at most, the first communication node donot necessarily transmit the demodulation reference signal through sixports in each slot. In particular, in a cell with fewer users whorequire fewer demodulation reference signal ports, for example, if onlyuser #1 in the cell uses one port, port p1 as shown in FIG. 7 , on thetime-domain symbol occupied by the demodulation reference signal,remaining eight REs other than four resource elements (Res) occupied byport p1 may be used for data transmission. In other words, since portsp3 to p6 are not used for sending demodulation reference signals, eightREs occupied by ports p3 to p6 may be used for data transmission. Inthis case, if the base station sends data to user equipment (UE) #1 onresources occupied by ports p3 to p6, the ports of the data of UE #1 andthe demodulation reference signal of UE #1 use the frequency-divisionmultiplexing (FDM).

However, if another user UE #2 in the cell occupies ports p3 to p6, theresources on ports p3 to p6 cannot be used for sending data to UE #1.Therefore, for UE #1, the base station cannot send the data to UE #1 onthe resources occupied by ports p3 to p6. Therefore, additionalsignaling may be required for notifying whether the data and thedemodulation reference signal of UE #1 may use the FDM.

However, since the number of symbols of the slot is greater (that is, X1is greater), that is to say, a great number of resource elements may beused for sending the data, for UE #1, it can be predefined that no datais sent on the time-domain symbol occupied by the demodulation referencesignal, so that no additional dynamic control signaling is needed fornotifying the user whether the multiplexing mode of the data and thedemodulation reference signal includes the FDM because the demodulationreference signal and the data of the user always use predefined timedomain multiplexing (TDM). In this case, since the number of symbols ofthe slot is greater and the number of resource elements available to thedata is also greater, as shown in FIG. 7 , a total of 120 REs on symbol5 to symbol 14 are available, so that even if the resources on ports p3to p6 are used for data transmission, the transmission efficiency can beincreased to a small extent and is only 8/120 and less than 7%.Moreover, if the resources on ports p3 to p6 are not used for datatransmission, power of the demodulation reference signal of the user canbe increased, that is to say, transmit power on ports p3 to p6 may belent to ports p1 and p2. The power ratio of the demodulation referencesignal p1 to the data is 3:1, i.e., greater than Y, which is, forexample, 1.

Therefore, if the size of the configuration resource refers to thenumber of time-domain symbols included in the slot, when the number ofsymbols included in the slot is greater, the multiplexing mode of thedemodulation reference signal and the corresponding data cannot be theFDM, that is, the multiplexing mode can only be the TDM and thedemodulation reference signal and the corresponding data are notsimultaneously transmitted. In this case, there is a limitation that thenumber of time-domain symbols of the demodulation reference signalincluded in the sending unit is less than X3, for example, the number isequal to 1 or 2, that is, X3 is equal to 2 or 3. In this case, thedemodulation reference signal tends to occupy a small number of symbols,for example, only 1 symbol or 2 symbols. Otherwise, a huge waste will becaused if no data is transmitted on the time-domain symbol occupied bythe demodulation reference signal.

However, if the slot where the demodulation reference signal is locatedincludes a small number of time-domain symbols, for example, the slot isa slot including seven time-domain symbols or a mini slot including, forexample, only two time-domain symbols, the huge waste will be caused ifno data is transmitted on the time-domain symbols of the demodulationreference signal by default. This is because the remaining eight REsoccupy a great proportion of resources on a total of seven symbols ifthe number of ports is smaller, for example, the base station only sendsport p1 to UE #1. If the slot has only two time-domain symbols, even ifthe overhead of a control channel is not considered, one PRB onlyincludes 24 REs and the proportion of resources occupied by ports p3 top6 in the slot is one third. In this case, additional signaling isrequired for notifying whether the demodulation reference signal and thecorresponding data may use the FDM. Of course, if the slot includes asmall number of symbols and can support a limited number of ports of thedemodulation reference signal, it can be regarded by default that thedemodulation reference signal and the corresponding data may use theFDM. In other words, when the number of symbols of the configurationresource is less than or equal to X1, the multiplexing mode of thedemodulation reference signal and the corresponding data includes theFDM. In this case, the number of symbols of the configuration resourcerefers to the number of time-domain symbols included the sending unit orthe number of time-domain symbols included in the scheduled resourceallocated to the second communication node. When the number of symbolsof the configuration resource is less than or equal to X1, the powerparameter ratio of the demodulation reference signal to thecorresponding data is less than or equal to Y; when the number ofsymbols of the configuration resource is greater than X1, the powerparameter ratio of the demodulation reference signal to the data isgreater than Y, where Y is an integer, e.g., Y=1. In this case, sincethe slot includes a small number of symbols, the data needs to be senton unused ports, and power cannot be lent, the power ratio of thedemodulation reference signal to the data is 1:1. The power ratio hereinis described for each DMRS port and corresponding data layer.

In this embodiment, when the number of symbols of the configurationresource is less than X2, the multiplexing mode of the demodulationreference signal and the corresponding data does not include the FDM.The number of symbols of the configuration resource refers to the numberof time-domain symbols of the demodulation reference signal included inthe sending unit. In this case, when the number of symbols of theconfiguration resource is less than X2, the power parameter ratio of thedemodulation reference signal to the corresponding data is greater thanY; and when the number of symbols of the configuration resource isgreater than or equal to X2, the power parameter ratio of thedemodulation reference signal to the data is less than or equal to Y,where Y is an integer. The number of time-domain symbols included in thesending unit or the scheduled resource tends to be greater than X4, forexample, a sending slot includes 14 symbols.

That is to say, if the number of demodulation reference signals in theslot is too small, i.e., less than X2, for example, X2=3, and the numberof demodulation reference signals is equal to 2, or X2 may also be equalto 2 and only 1 DMRS symbol exists in the slot, fewer remainingresources on the symbols of the demodulation reference signal are usedfor transmitting the data, and the DMRS and the data cannot use the FDMby default and can only use the TDM. Since no data is sent, the powerratio of the demodulation reference signal to the corresponding data isgreater. That is, a format of the slot or the number of symbols includedin the slot is bound to the multiplexing mode of the demodulationreference signal and the data, so that in some cases, no additionaldynamic signaling is required for notifying the user of the multiplexingmode of the demodulation reference signal and the data. In the examplesdescribed above, the number of symbols included in the slot tends to begreater, that is, X4 is greater.

However, if the demodulation reference signal occupies a great number oftime-domain symbols, for example, FIG. 8 is a schematic diagram of thedemodulation reference signal in this embodiment, as shown in FIG. 8 ,the demodulation reference signal occupies 4 time-domain symbols. Sincethis situation is a single-user scheduling, it can be regarded that themultiplexing mode of the demodulation reference signal and the dataincludes the FDM. In this case, the power ratio of the DMRS to thecorresponding data may be lower, e.g., 1:1. In other words, when thenumber of symbols of the configuration resource is greater than X2, themultiplexing mode of the demodulation reference signal and thecorresponding data includes the FDM. The number of symbols of theconfiguration resource refers to the number of time-domain symbols ofthe demodulation reference signal included in the sending unit. In thiscase, when the number of symbols of the configuration resource isgreater than X2, the power parameter ratio of the demodulation referencesignal to the corresponding data is less than or equal to Y; and whenthe number of symbols of the configuration resource is less than orequal to X2, the power parameter ratio of the demodulation referencesignal to the data is greater than Y, where Y is an integer. The numberof time-domain symbols included in the sending unit or the scheduledresource is greater than X4, for example, the sending slot includes 14symbols. X includes X1, X2, X3 and X4. A value of Y may be predefined.Optionally, X may be notified through the higher-layer signaling, e.g.,RRC signaling.

When information about the configuration resource is used for indicatinga time-domain spacing of the demodulation reference signal in thesending unit, if the spacing is less than Z, the multiplexing mode ofthe demodulation reference signal and the corresponding data does notinclude the FDM; and if the spacing is greater than or equal to Z, themultiplexing mode of the demodulation reference signal and thecorresponding data includes the FDM. In this case, the sending unitshould include multiple demodulation reference signal symbols. Thepresent disclosure generally refers to that only 2 DMRS symbols exist inthe sending unit. One sending unit or one receiving unit refers to oneslot and one slot generally includes 14 time-domain symbols.

When the configuration resource is used for indicating the time-domainspacing of the demodulation reference signal in the sending unit, if thespacing is less than Z, the power parameter ratio of the demodulationreference signal to the corresponding data is greater than Y; and if thespacing is greater than or equal to Z, the power parameter ratio of thedemodulation reference signal to the corresponding data is less than orequal to Y.

If the allocated demodulation reference signal occupies 2 symbols in theslot and a spacing between the two symbols is less than Z, e.g., Z=2,the spacing between the two symbols is 1, i.e., the two symbols areadjacent. In this case, the base station configures two adjacent DMRSsymbols to schedule more DMRS ports for multiple users or a single user,so no data needs to be sent on the DMRS symbols, that is, themultiplexing mode of the demodulation reference signal and thecorresponding data does not include the FDM. FIG. 9 is a schematicdiagram of DMRS ports allocated to a user in this embodiment. As shownin FIG. 9 , if 8 DMRS ports are allocated to the user and are ports p1to p8, resources occupied by ports p9, p10, p11 and p12 are not used forsending the data. In this case, power of the resources occupied by portsp9, p10, p11 and p12 may be lent to the ports of the user, and the powerratio of the DMRS to the data of the user is greater than 1. That is,when the configuration resource refers to the time-domain spacing of thedemodulation reference signal in the sending unit, the power parameterratio of the demodulation reference signal to the corresponding data isgreater than Y when the time-domain spacing is less than Z, where Y=1.Since no data is transmitted on the symbol where the DMRS is located bydefault, no additional signaling is required for notifying whether datais transmitted on ports p9 to p12, thereby saving the overheads.Otherwise, additional signaling is required since ports p9 to p12 mayalso be allocated to other users (multi-user scheduling).

However, if the spacing is greater than or equal to Z, the multiplexingmode of the demodulation reference signal and the corresponding dataincludes the FDM. In this case, the sending unit should include 2demodulation reference signal symbols. FIG. 10 is a schematic diagram ofDMRS symbols in this embodiment. As shown in FIG. 10 , the spacingbetween two DMRS symbols is greater, e.g., greater than Z, where Z=4. Inthis case, the base station configures two DMRS symbols with a greaterspacing to estimate high Doppler influence, so the user has a higherspeed. For a high-speed user, the multi-user scheduling is generallydifficult to be performed, that is, single-user scheduling is performed.In this case, if the port allocated to the user by the base station isport p1, REs occupied by ports p3 to p6 may be used for sending the dataand no additional signaling is required for notification since resourcesoccupied by ports other than port p1 cannot be occupied by other users.That is, the multiplexing mode of the demodulation reference signal andthe corresponding data includes the FDM, that is, the demodulationreference signal and the corresponding data may be simultaneouslytransmitted. In this case, due to the data transmission, the power ratioof the demodulation reference signal to the corresponding data is 1:1,that is, less than or equal to Y, where Y=1.

The FDM in this embodiment does not refer to that the DMRS and the datahave to use the FDM. For example, a user occupies ports p1 to p6 in FIG.10 , and the data and the DMRS cannot be simultaneously sent. Therefore,including the FDM herein refers to that the FDM may be executed, and notincluding the FDM herein refers to that the FDM may not be executed.

In this embodiment, the multiplexing mode of the data and thedemodulation reference signal is implicitly determined according towhether two demodulation reference signal symbols are adjacent, so thatsignaling overheads are saved. Otherwise, explicit dynamic signaling hasto be used for indicating the multiplexing mode.

This embodiment provides another signal sending method. The method mayinclude the content described below.

A first configuration resource and a third configuration resource aredetermined. A sending mode of a signal sent by using the firstconfiguration resource includes a sending mode of time-domain codedivision multiplexing. A sending mode of a signal sent by using thethird configuration resource includes a sending mode other than thetime-domain code division multiplexing.

A resource intersection in the time domain of the signal sent by usingthe first configuration resource and the signal sent by using the thirdconfiguration resource in time domain is an empty set.

In some embodiments, the signal sent by using the first configurationresource includes at least one of: an uplink demodulation referencesignal, a downlink demodulation reference signal, a channel stateinformation-reference signal or an uplink control channel.

The signal sent by using the third configuration resource includes atleast one of: the uplink demodulation reference signal, the downlinkdemodulation reference signal, the channel state information-referencesignal or the uplink control channel.

If a time domain sending mode other than code division multiplexing maybe TDM or simple port repetitions. The resource intersection in the timedomain of the signal sent by using the first configuration resource andthe signal sent by using the third configuration resource is the emptyset. That is, for a same user, a base station will not simultaneouslyconfigure the signal sent by using the first configuration resource anda signal in a third configuration resource for the user. Alternatively,the base station will not simultaneously send the signal sent by usingthe first configuration resource and the signal in the thirdconfiguration resource to the user. The signal sent by using the firstconfiguration resource and the signal in the third configuration set aredifferent in type. From the perspective of the user, the user does notdesire to be simultaneously configured with the signal sent by using thefirst configuration resource and the signal in the third configurationresource. That is, the user cannot be configured with a phase trackingreference signal if the user is configured with the signal sent by usingthe first configuration resource, or the user does not desire to beconfigured with the demodulation reference signal, the CSI-RS, the PUCCHor the like with the time-domain code division multiplexing mode if theuser is configured with the phase tracking reference signal, or the userdoes not desire to simultaneously receive the signal sent by using thefirst configuration resource and the signal in the third configurationresource.

This is because the signal sent by using the first configurationresource adopts the time-domain code division multiplexing which canonly work well without phase noises. If the user is simultaneouslyconfigured with signals sent by using the third configuration resourceand these signals are configured to use the multiplexing mode other thanthe time-domain code division multiplexing, that is, it is assumed thatthe phase noises exist, a contradiction occurs in an implementation ofthe user. The user needs to implement two demodulation methods, whichcauses a higher slot complexity for the user.

For example, if the signal sent by using the first configurationresource is the downlink demodulation reference signal (DMRS) whosemultiplexing mode on two consecutive OFDM symbols is the code divisionmultiplexing, and a signal sent by a second configuration resource isthe channel state information-reference signal (CSI-RS) whosemultiplexing mode on two or four consecutive OFDM symbols is the timedivision multiplexing (TDM), the base station cannot simultaneouslyconfigure the CSI-RS and the DMRS for the user, or the base stationcannot simultaneously send the CSI-RS and the DMRS to the user. That is,the user does not desire to be simultaneously configured with the CSI-RSand the DMRS, where the time-domain multiplexing modes of the CSI-RS andthe DMRS are different, that is, the time domain CDM and themultiplexing mode other than the time domain CDM. Alternatively, theuser does not desire to simultaneously receive the CSI-RS and the DMRS,where the time-domain multiplexing modes of the CSI-RS and the DMRS aredifferent, that is, the time domain CDM and the multiplexing mode otherthan the time domain CDM. The CSI-RS and the DMRS are configured onconsecutive OFDM symbols.

It is to be noted that a signal multiplexing mode in this embodiment isgenerally limited on adjacent or consecutive time-domain symbols becausethe time-domain code division multiplexing has a poor effect if thesignal sent by using the first configuration resource or the signal sentby using the third configuration resource are not sent on theconsecutive time-domain symbols. Therefore, the signal sent by using thefirst configuration resource or the signal sent by using the thirdconfiguration resource is configured on multiple consecutive time-domainsymbols.
